Pontus or Venus - which inputs and cables

Assuming the DAC has a better clock I’d use USB from the A6 and most likely i2S from the SMSL.  Digital cables matter a lot so don’t skimp.  Hope this helps. 

USB from Eversolo to Denafrips. 
you will need to try AES and i2s from smsl. 
Audioquest Diamond USB or Audience StudioOne should be smooth and least digital sounding (you’re looking for that natural smooth sound to resemble your analog). 
For i2s I can’t recommend any cables…never used it. 
For AES or coax cable you can try Kimber D60. This is a well established workhorse. Should be very nice. This one is sold by Kimber Kable with full warranty and 30 days return. https://ebay.us/m/mhO0oY

I had Eversolo A6 Master (now have T8 same configuration) going USB (In-akustik USB cable-expensive but best there is according to Small Green Computer and worth the $) to DENAFRIPS Hermes DDC which then feeds Pontus II 12th DAC via I2S. I am using the Tubulus Aregentis I2S cable, also a bit costly but worth it. I am thrilled with this setup. Hope this helps…

Best of luck!
